Fantastic to get the feedback. Congrats to you, and others, that may have saved some "bad statistics" over the years.
Yes, I remember that sign at RS.

I believe it was in this discussion, I have also had students (usually in a 2-33) "throw up their hands" when something odd happened (may even have been because I set it up, or, let them get deep) just to see what they would do when stressed. If they threw their hands up, and we had altitude, I would calmly put my hands on their shoulders and say something like, "It's still your airplane, start doing pilot stuff".

A couple times I had to fly it out, then we had a long ground discussion.

I always let them know, I would "let them get in over their head, never let them get over MY head".
Goal was not to scare them, but to push their limits a bit at a time in a sorta controlled environment.

Congrats again!
